Soil Physical Effects of Pneumatic Subsoil Loosening Using Aterralift Soil Aerator    (View PDF)

Kaj Rolf

Abstract: The effects of pneumatic subsoiling using a Terralift soil aerator on a number of soil physical parameters were measured at sites with sandy loam and loam over clay loam, respectively. The subsoil was compacted under controlled conditions prior to aeration. In the sandy loam, aeration led to a decreased bulkdensity, an increase in porosity (mainly as an increase in macro-porosity) and an increase in saturated hydraulic conductivity and air permeability. Penetration resistance was lowered at this site. After aeration at the loam soil site, measurements indicated that bulk density increased, porosity decreased, there were no changes in saturated hydraulic conductivity and only a small increase in air permeability.
